Within the class of Reservation Random Access (RRA) protocols, RRA-ISA operates over a TDMA framed channel in a cellular structure, with the aim of maximizing the one-step throughput over an entire frame. In the presence of mixed (e.g., voice and data) traffic, an additional dynamic bandwidth allocation technique has been introduced, in order to give a better service to the real-time traffic, subject to a quality constraint, by slightly increasing data packet delay. Several comparisons show a relevant performance improvement (in terms of data delay and maximum number of voice stations acceptable within a cell) over other protocols.

Abstract
Within the class of Reservation Random Access (RRA) protocols, RRA-ISA operates over a TDMA framed channel in a cellular structure, with the aim of maximizing the one-step throughput over an entire frame. In the presence of mixed (e.g., voice and data) traffic, an additional dynamic bandwidth allocation technique has been introduced, in order to give a better service to the real-time traffic, subject to a quality constraint, by slightly increasing data packet delay. Several comparisons show a relevant performance improvement (in terms of data delay and maximum number of voice stations acceptable within a cell) over other protocols.
